When the lifting height of a certain track bed plate reaches 30mm, fix the leveling gasket, dismantle the lift there, install it on the sleeve of the adjacent track bed plate, and repeat the previous lifting steps. Repeat the above steps until the lifting height of the entire track bed plate reaches 30mm. Finally, a measuring instrument is used to check the level of each track bed board. If leveling is required, the lifting mechanism can be reinstalled for local fine-tuning.
